Control Panel Display 
The following table lists the control panel display that can appear if an error occurred during a 
firmware update, and explains the likely causes of the display and what action to take when 
they appear. 
Display  Likely Cause  Solution 
The Home screen (touch panel models) 
or “Ready” (four-line LCD models) does 
not appear on the control panel after one 
minute following a firmware update. 
A power failure or similar 
interruption prevented 
the update from 
completing. 
Refer to "If Initialization 
Does Not End Following 
a Firmware Update". 
Control Panel Indicator Patterns (Only for Four-line LCD Models) 
The indicators of the control panel show the machine’s status during and after firmware updates. 
If an update fails or does not complete normally, refer to the following table to resolve the 
problem. 
Indicator Pattern  Likely Cause  Solution 
The Alert and Data in 
indicators light up 
simultaneously 
If the Alert and Data in indicators light up 
simultaneously after you turn the machine’s 
power back on following a firmware update, the 
update did not complete due to a power failure 
or similar interruption. 
Refer to "If 
Initialization Does 
Not End Following a 
Firmware Update".
